Test chart structure

The "ISO 12642-2 / ANSI IT8/7.4 Random" test chart contains the same 1617 patches as the "ISO 12642-2 / ANSI IT8/7.4 Visual" test chart.
However, the patches in this test chart are rearranged so that ink is always applied evenly to the ink zones during printing. The test chart can be printed both in longitudinal and cross direction.
